I-beam is a long steel strip with an I-shaped cross section. It has high strength and toughness as well as strong resistance to external forces. It is widely used in construction, bridges, power stations, oil drilling platforms, railways and other fields.

Angle steel is a long steel strip with two sides perpendicular to each other at right angles. There are equal-leg angle steel and unequal-leg angle steel. It has strong bearing capacity and good corrosion resistance. It is a multifunctional steel product that is widely used in machinery manufacturing, shipbuilding, railways and bridges.
